COMBINATION SEED DISPENSER..

Application led November 3, 1923. Serial No. 672,550.

To all wwm it may concern.'

Be it known that I, JOHN A. BURCHAM, a .citizen of the United States, residing at Bath Springs, in the county of Decatur and State of Tennessee, have invented certain new and useful Improvements in a Combination Seed Dispenser; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to an agricultural implement for planting .seeds and has for its object to provide an implement adapted for planting simultaneously two different kinds of seed such for instance as corn and peas.`

A further object of the invention is the provision of `means whereby vthe quantity of seed deposited in a hill may be `regulated and furthermore to insure a positive discharge of the predetermined amount of seed to be delivered.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

`While the drawings illustrate an embodi-` ment of the invention it is to be understood that in adapting` the same to meet different` conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to Without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application.

Figure 1 is a side View of a combined planter and fertilizer distributor embodying the invention,

Figure 2 is a top plan view thereof,

Figure 3 is a sectional detail view of the forward hopper and distributing mechanism associated therewith on the line 3-*8 of Figure 7,

Figure 4 is a view of the part shown in Figure 3 as seen from the bottom side, the bottom plate being omitted,

Figure 5 is a detail sectional View on the line 5-5 of Figure 4, the upper portion of the inner hopper being broken away,

Figure 6 is a view of the forward hopper inverted showing more clearly the means for throwing the distributing mechanism into and out of gear,

Figure 7 is a top plan view of the forward hopper and parts associated therewith on a larger scale,

nated in the several views of the drawings by like reference characters.

The implement vcomprises a runner frame 1 and a wheel frame 2 which may be of .any usual or preferred construction and arrangement, each of the `frames being provided with a distributing mechanism..A The ground wheel 3 is fast to an axle 4 upon which' is mounted a sprocket wheel 5 and a beveled gear wheel 6. Handle bars 7 are provided for manipulating the implement in a. marmer well understood. The usual covering blade 8 is located at eachside of the implement for covering the seed which is deposited in the furrow or trench formed by the runner 9 in a manner well understood. i

The mechanism for planting seed such as corn and peas and for distributing fertilizer is mounted upon therunner frame or forward portion of the implement and com-V prises anouter hopper 10 which is fixed and an inner hopper 11 concentric with the outer hopper and mounted to rotate. A plate 12 closes the bottom of the hopper 1.() and is stationary. The plate A12 is formed with two Vopenings 13 and 14 which are comprised within theupper end of a. spout o1" tube 15 which conveys the `seed or seed and fertilizer to the trench or furrow formed by the runner 9. An annularrecess 16 is formed in the top Vside ofthe plate 12 and receives a toothed ring 17 which is brazed or otherwise attached to the lower end of the inner hopper 11. Distributing plates 18 and 19 are supported upon the bottom plate 12, are brazed or otherwise fastened to hopper 11 and the latter to ring 17, and are rotatable with the hopper. 11. The toothed ring 17 is attached to the bottom side of the plate 18 and is in mesh with a bevel gear 20 splined to a shaft 21 which is connected at its outer end to a longitudinal shaft 22 by moving-saidfbevel gear in't'oan-d out of enL gagementwiththe toothed ringi 17 whereby to throw the forward distributing mechanism into or out o fgeary asrzerpiired;v The shaft 22 is provided'at its lower rear end with a beveled gear 25 which isw infmeshV withthe beveled gear 6 whereby to derive movement from the shaittor"t aixlewll. Thei Idistributing plate 18 is provided with a plurality of openings 26 which are-t-adap'ted to register with the openingalB 'of'tliebotl toni` plate v12.V 'Dhe'v'distribnting plate r19 is formed with' a'n plurality ofi openings-1 27 which are adaptedfto register with thefopeng ing 14@ of the plate. 12.f A'inedrguard 28de disposed' about the' plate' 197 and an edge portion is beveled and arranged to=cover1the` openings=27z An edge portionioftliefguard 28: is`A cut' awayAV as findicated; at 29 to 'f admit' of the openings 2.7 being',successiveljyv.y ext posed so as to reo-eiveseedrorfertilizer 'from the 'hopper'v 11.
